TOP248Y datasheet by Power Integrations

TOP248Y Frequently Asked Questions (FAQs)

• What is the maximum output power of the TOP248Y?
  The maximum output power of the TOP248Y depends on the input voltage, output voltage, and the transformer turns ratio. However, as a general guideline, it can deliver up to 65W of output power.
• How do I select the right transformer for the TOP248Y?
  The transformer selection depends on the input voltage, output voltage, and the desired output power. Power Integrations provides a transformer selection guide and a transformer design tool to help with the selection process.
• What is the purpose of the BYPASS pin on the TOP248Y?
  The BYPASS pin is used to bypass the internal startup circuitry and allow the use of an external startup circuit. This pin can be connected to an external voltage source or a capacitor to provide a startup voltage.
• How do I implement overvoltage protection (OVP) with the TOP248Y?
  The TOP248Y has a built-in OVP circuit that can be enabled by connecting a resistor between the OVP pin and the input voltage. The OVP threshold can be set by selecting the appropriate resistor value.
• What is the maximum operating temperature of the TOP248Y?
  The maximum operating temperature of the TOP248Y is 150°C. However, the device can operate up to 120°C with derating.
